DOOR OR WINDOW FASTENER.

SPECIFICATION forming part of Letters Patent No. 777,342, dated December 13, 1904.

Application filed May 14, 1904. Serial No. 207,936.

To all whom, it may concern:

Be it known that I, EMIL HOMER, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Door or Window Fasteners, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whicl Figure 1 is a fragmentary view of a pair of window-sashes, showing my invention applied thereto. Fig. 2 is a View through a door and jamb, showing myinvention applied. Fig. 8 is a perspective view of one of the locking members. Fig. 4C is a cross-sectional view through the bottom rail of the top sash and the top rail of the lower sash, showing the positions of the fastener to prevent relative movements of the respective sashes. Fig. 5 is a perspective view of the locking parts. showing their relative positions for transporting; and Fig. 6 is a detail perspective view of the slidable locking part.

This invention relates to door and window fasteners, the primary object being to provide a portable fastener which can readily be applied to or removed from a window or door, so as to provide a convenient means for locking the window or door.

Another object of the invention is to provide means whereby a fastener may be con veniently carried in the pocket without the liability of marring or tearing the fabric thereof; and a still further object is to provide an efficient, durable, and inexpensive fastener capable of performing all of the services for which a device of this character might be used.

The reference-numeral 1 designates one of the locking members, which comprises a Hat plate having slits 2 and 3 formed therein to provide a longitudinally-disposed intermediate spring-iinger 4, on one face of which are projections or teeth 5, running transverse of the finger 4:, which finger is of greater length than either of the side fingers 6 and 7. At one end of the plate 1 is a right-angularly disposed anchor or spur 8, adapted to be (No model.)

forced or driven into one rail of a window or into the door-frame. A cooperating part is provided for the member 1, which is adapted to slide thereon, and this member is illustrated as comprising a slide n'eferably stamped up or formed of sheet metal and provided with overlapping lips or projections 9 and 10, forming grooves for the reception of the fingers 6 and 7'.

An otl'setted projection or abutment 11 is provided on the second or cooperating member, from which is stamped or otherwise formed a rigid tooth or pawl 12 for engagement with any one of the series of teeth or projections 5 on the linger L.

In applying the device as a window-fastener the anchor or prong on the end of the plate is preferably inserted into the side of the bottom rail of the top sash, so that the blade is interposed between the opposite faces of the bottom rail of the top sash and the top rail of the bottom sash. The slidable member is then caused to engage with the plate, so that the tongue 12 will engage the proper tooth or projection on the linger a, as indicated in Fig. 1. When the slidable member is moved down upon the plate so that the abutment rests upon the top rail of the lower sash, the two sashes will be held rigid with relation to each other and any tendency to independent movement will be prevented.

1n applying the device as a door-fastener the anchor or spur may be inserted into the door frame so that the plate will extend through the space between the door-jamb and the edge of the door, as indicated in Fig. 2. The cooperating member can obviously be slid upon the plate so as to prevent the door swinging on its hinges until the member is removed. By providing the spring-linger L the end 13 thereof may be grasped to move the teeth into and out of engagement with the tooth 12 of the slidable member, thus facilitating the application and removal of the slidable member. The slidable member so arranged that it can be reversed and slid upon the member 1, as indicated in Fig. 5, in which position it is preferably placed to act as a guard for the spur when not in use.

I am aware that minor changes in the con- I00 struction, arrangement, and combination of the several parts of my device can be made an anchor portion and a yielding toothed and substituted for those herein shown and described without in the least departing from the principle and nature of my invention.

Having thus described the invention, What is claimed as new, and desired to be secured by Letters Patent, is-

1.v A door and window fastener comprising two members, one of which is a plate having an anchor portion at one end, said plate being provided with a yielding portion having teeth, and a second member slidable upon the plate and provided with a tooth for engagement with the teeth on the yielding portion of the plate; substantially as described.

2. A door and window fastener comprising two members, one oi which is provided with linger, and a second member cooperating with the first-named member, said second member being slidable upon the first-named member and having a rigid part for engagement with the toothed yielding finger; substantially as described.

In testimony whereof I hereunto aliix my signature, in the presence of two witnesses, this 11th day of May, 1904.

EMIL HOMER.
